Rules
- Normal Sudoku rules apply: Place the digits 1–9 in every row, column, and 3×3 region.
- Equal-sum line: (blue lines) Box or region borders divide a blue line into segments that have the same sum. Different lines may have different sums.
- Killer cages: Each cage’s digits sum to the small number in its top-left corner. No digit repeats within a cage.
- Thermometer: (gray lines) Digits along a thermometer increase from bulb to tip.
Enjoy! There’s no shame in using the killer calculator.
Solution code: Bottom Row (left to right)

Have to agree with ketchup_monster on not needing killer calculators.

Extremely beautiful puzzle. Once the solve starts flowing, it is so smooth that you won't need any killer calculators. The puzzle guides you towards the solution after the break in. Amazing construction!
